I'm not really interested in bringing this up anymore now that I have my own fork but let me just point out that as long as there's only a windows version then you're never going to be able to pool that many GPUs together, because NVIDIA/AMD drivers and PCI cards limit the amount of GPUs you can attach at once and there is no MPI-kind of code for serving other machines Bitcrack shares like Kangaroo has (as primitive as it may be).
